Vegan diet have no good things. Vegan diet suck. Vegans crazy to follow vegan diet. Feel sorry for them.
After three years of a "female problem" that kept me confined at home at least one day a month for fear of an accident, and no health insurance but fearful of what would be found if I went to Planned Parenthood (I have a young daughter), I read something on the Weston Price website about vitamin A being important for reproductive health, and how some people can't convert beta carotene well enough to benefit from it. I was getting beta carotene in vegetables and supplements. I got worried. I started taking retinol derived from fish oil.
I got better. My cycle even normalized.
Did some more digging and come to find out that not only can't infants and young children convert beta carotene to vitamin A, A is also important in several developmental processes in utero. If babies can't convert beta carotene, it follows fetuses can't either. Even worse, experts are telling moms not to eat liver while pregnant, for fear of birth defects. But in my digging I found out embryos are perfectly capable of regulating how much vitamin A is in their systems. I'm going to guess fetuses are too, although the study didn't cover that. Yet another lie from Mainstream Nutrition. Or a bunch of yahoos pronouncing things from on high without doing their due diligence.
My girl paid the price well before I had problems. She was born with defects to her eliminatory system such that the valves in her bladder didn't work right and her urine would reflux back into her kidneys. Her right kidney is also noticeably undersized--some asymmetry is considered normal, but hers was extreme. In my research I found this is one of the developmental processes vitamin A mediates--it determines how the ureteral bud will develop, into both the nephrons (filtering structures) in the kidney as well as the ureter itself (tube going into the bladder). The kidney develops later in pregnancy. That probably explains why she's not vision-impaired too. I must have had enough stores to develop her eyes but started running low later in pregnancy. Good lord.
That's just vitamin A. Think about all the infertile people out there. Or about the fact (according to the Mayo Clinic) that urinary tract defects are the most common birth defects in the Western world. A lot of cases of VUR (the developmental problem my daughter had) go undiagnosed because they're not severe enough to get a doctor's attention. For that matter, there are a lot of little kids needing glasses, even if they're not blind.
Now consider that on a vegan diet, we can't get methylcobalamin (proper form of B12), vitamin D3 (you can only find D2 in mushrooms--there is no D in any other non-animal food, and sunshine's not always enough), vitamin K2 mk-4 (most vegetable foods only have K1, poorly converted), or a whole lot of minerals that are not bound up in some noxious chemical or another. Especially not if you eat all your veggies raw.
A vegan can get away with it for a while if they were healthy to begin with, or if they are not too far damaged. With several of the vitamins you store them for a while. Some of the B vitamins fall into this category even though they're water-soluble; so does A. But that's going to run out eventually. You'll feel good now, dumping the SAD junk food. You will feel like crap later if you keep up the way you are going. Just ask Lierre Keith. Even for vegans who stay the course, I hear a lot of them cheat from time to time. With cheese, of all things. Guess they are really missing their vitamin K2.
Do what you want, but don't think for a minute we don't consider our dietary habits as well, just because we didn't make your choice. And we based ours in science, not in feelings about cute widdle fuzzy animals. I have five cats. Don't tell me I don't like animals. I think they'd hotly disagree with you.
